if you do take a vitamin d supplement always consume it with K2 and best to just get it from sunlight and liver (has natural k2 to vitamin d3 ratio) otherwise taking vitamin d3 in isolation overwhelms you body with sequestered calcium

this is @Paul Saladino MD organization and i owe him a lot of gratitude for his original carnivore book that opened my eyes to the ancestral animal based diet we forgot in the modern age. before that i floundered with plant based diets and all the standard teachings of medical school vilifying cholesterol and pushing vitamin supplements.

vitamin D has never been isolated from humans in a form distinct from vitamin D₃ (cholecalciferol). In humans, only vitamin D₃ has been identified This compound is produced in the skin when 7‑dehydrocholesterol is irradiated by UV‑B light. The term "vitamin D₁" was initially used but was later discovered to be an artifact—a mixture of vitamin D₂ and another compound The first pure vitamin D to be isolated and identified was vitamin D₂ (ergocalciferol), but this was from plant/fungal sources (like irradiated yeast), not from humans

some hidden truths about vitamin d3 supplements (Cholecalciferol) (it is an active ingredient in rat poison) The hormone form of D signals your intestines to preferentially absorb calcium over magnesium. Magnesium is anti-inflammatory; calcium is inflammatory D3 from wool which is coated in lanolin (sebaceous gland secretions)gets washed with industrial detergents. The extracted lanolin then undergoes a "dehydrobromination reaction" using either 2,4,6-trimethylpyridine (derived from coal tar) or a cocktail of sodium hydroxide, potassium hydroxide, N-Bromosuccinimide, and chloroform. D3 toxicity typically requires doses above 10,000 IU daily for months when you get your "vitamin D" level checked the lab is testing for the presence of synthetic markers – specifically, they're measuring 25-hydroxyvitamin D, which is what your liver creates from cholecalciferol. The Inuit, living in darkness for months, eating a diet of seal and whale – no rickets, no vitamin D deficiency. Traditional cultures worldwide, no access to supplements, no fortified foods, yet no epidemic of bone diseases.

i really like this flu study. what causes the flu in equator level counties if it isn't from the cold, isn't from being indoors on a seasonal basis and isn't from changes in relative humidity "Through this, we show that influenza in Vietnam does not show consistent timings, making preparedness efforts such as vaccination campaigns difficult to design."

Author summary Much of the world experiences influenza in yearly recurring seasons, particularly in temperate locations. Such seasons occur each ye...

this is the explanation for why the flu is seasonal: 1. Viral Stability in Cold, Dry Air: Influenza viruses survive better and remain in the air longer when the air is cold and dry. Low absolute humidity (the total amount of water vapor in the air, which is lower in winter even when relative humidity is high) allows the tiny respiratory droplets that carry the virus to stay suspended for longer periods and travel farther. 2. Host Immune Response: Cold, dry winter air can also impair our innate immune defenses. The mucociliary clearance system, which is the layer of mucus and tiny hairs (cilia) in our respiratory tract that traps and clears out pathogens, works less efficiently in these conditions 3. Human Behavior: During colder months, people spend significantly more time indoors in closer proximity to one another. This increased crowding in homes, schools, and offices facilitates easier transmission of the virus through respiratory droplets and aerosols. does this sound logically coherent to you?

there are no conditions that would survive from an evolutionary perspective that severely disabled young people before having children. you should not be hearing about young adults and teenagers having strokes and heart attacks.

a common statement in infectious disease: "if something is highly infectious and not lethal it spreads far but highly lethal and infectious won't spread" ask yourself: if something kills a host very quickly and people learn to avoid that sick person so they don't immediately die, how does the "virus" continue to exist?

the best peer review is scientific experiment replication. if different groups do the same experiment over and over and get the same result there is no need for peer review. replication is the only valid peer review.

the only thing that can be tested in a randomized double blind placebo controlled trial is a pharmaceutical intervention. everything else, even if randomized gets labeled as lesser quality evidence. (can't test organ meat ingestion and exercise this way) this is why evidence based medicine has been co-opted by drug based interventions. those molecules get the highest stamp of evidence based guidelines

file this under the obvious for must of here but a shocker for the mainstream. high saturated fat creates the cholesterol building blocks for a healthy brain "Consumption of ≥50 g/d of high-fat cheese (>20% fat) was associated with a reduced risk of all-cause dementia (HR 0.87; 95% CI, 0.78–0.97) and VaD (HR 0.71, 95% CI 0.52–0.96) compared with lower intake (<15 g/d). An inverse association between high-fat cheese and AD was found among APOE ε4 noncarriers (HR 0.87, 95% CI 0.76–0.99, p-interaction = 0.014). Compared with no consumption, individuals consuming ≥20 g/d of high-fat cream (>30% fat) had a 16% lower risk of all-cause dementia (HR 0.84, 95% CI 0.72–0.98). High-fat cream consumption was inversely associated with the risk of AD and VaD. " https://www.neurology.org/doi/10.1212/WNL.0000000000214343
